What Naturalization documents are needed if process was left incomplete?

I have my GGF Declaration of Intent, signed on 26 April 1918, six months before he died from “Spanish" flu. As I understand, he would have had to wait two years to file a Petition for Citizenship (unless he served in the military, which he didn’t). His WW 1 Draft Card from Sep 1918 identifies him as a declarant. As I understand, there were 3 copies of the DOI - one for the NY court, the Federal Naturalization Service, and the declarant. The FNS copy should be with NARA. USCIS should return a CONE indicating he never naturalized. Is there anything I’m missing?

I also have an Oath of Allegiance/Order Admitting Petitioner, signed by someone with the same very common name, on 14 May 1918. There’s nothing to connect that document with the DOI. Could he have been fast tracked for the war effort as a laborer? How likely is it that they are the same signer and how would I connect the two documents?

Check the 1920 US Census for him. If "Pa" (first papers) is noted in the citizenship column, (column 14) that would help to prove your case. Most consulates would want a certified copy (from NARA) in cases where the ancestor in question never naturalized.

Check the 1920 US Census for him.

He died in 1918, he’s not on the census. He died 6 months after signing the Declaration of Intent. I’m wondering if there’s anything I need from USCIS.
